Overview
Learn how to create a versatile Arduino-controlled rotary telephone prop for escape rooms in this comprehensive tutorial. Discover how to wire an Arduino or similar microprocessor directly to the mechanical components of a 1970s phone, including the rotary dial, hook switch, solenoid, microphone, and earpiece speaker. Explore the use of a DFPlayer Mini MP3 module for audio output and program custom behavior using a Finite State Machine (FSM). Master techniques for triggering incoming calls, handling outgoing calls to multiple numbers, and dynamically changing phone behavior during gameplay. Gain insights into integrating the prop with other escape room elements and controlling external hardware. Follow along with detailed explanations of hardware design, component identification, wiring, and Arduino code implementation. Perfect for escape room designers and DIY enthusiasts looking to create a flexible and feature-rich rotary telephone prop.
